Salary is important, but it’s not the only thing that contributes to job satisfaction. New research from Glassdoor reveals what makes people happiest at their jobs and how it varies depending on income.

Glassdoor wanted to see how employee values change as their income changes. What workplace factors do employees workers value overall, and how does it change with salary increases? To answer this, Glassdoor looked at their own data: salary reports and company reviews from over 600,000 users. They looked at six different factors: culture & values, senior leadership, career opportunities, business outlook, work-life balance and compensation & benefits.

They used the “Shapley Value” analysis method to see how various factors change the overall outlook. They explain:

In other words, under this approach, the six workplace factors can be thought of as a “pie” in terms of predictive power of employee satisfaction. We then add and drop factors from our model, and examine how the “pie” of predictive power changes with each adjustment — how more or less important a factor is to overall satisfaction. This approach allows us to identify which factors are the most statistically “important” predictors to overall employee satisfaction.

Overall, they found that culture and values were the biggest predictor of employee satisfaction, at 22% of the “pie.” Leadership quality was also important (21%) along with career opportunities (18%). Positive business outlook, work-life balance, and compensation and benefits were actually the least impactful predictors of employee satisfaction, according to Glassdoor’s analysis.

Unsurprisingly, compensation became less important as salary increased. After all, if your salary needs are met, it’s one less factor you have to worry about. When income increased, the most valuable factors mattered even more to employees: culture and values,the quality of senior leadership, and career opportunities.

Don’t let this data keep you from negotiating a higher salary, but if you’re looking for a job, it helps to know what other workplace traits matter. To check the report out for yourself, head to the links below.
